evaporation and codensation both are back bone of a water cycle. during evaporation water gets converted into vapors( gaseous form of water) due to heat. while during condensation , when temperature or heat comes down, the water vapors get condensed into tiny water droplets and form the clouds, and these clouds are the source of any means of precipitation like rain , hails, snow etc on the earth.so these both play very important role in water recycling on the earth
